BTW, I've taken the liberty of renaming the thread as our intention is that where a single lens is capable of being fitted to multiple mounts only one thread should be created and it's my judgement that preceding the thread name with "(Sony)" would have risked someone else creating a similar thread preceded by, say, "Nikon". Hope that's OK.

This lens can only be used on Sony DSLRs Bob. It's a special design by Zeiss for Sony, with AF and a modern appearance, unlike the MF-models for brands like Nikon and Canon.
Also, this lens gives different results than it's MF Zeiss equivalent, so I'd think the optical design is slightly different too.

Well, I'm glad I asked and thanks for the clarification. So, from the Sony USA site I now see that this is a Sony SAL85F14Z, albeit one with the added cachet of the Zeiss name on the barrel. That means it has to go in the Sony section of the Index so I'll follow the precedent of your Sony Carl Zeiss 24-70mm f/2.8 SSM thread and precede "Carl" with "Sony", but this time without the brackets. Sorry for the confusion.

Because of a whole lot of work for university (year's almost over), I haven't been able to take a lot of pictures with the 1.4/85 Zeiss, especially because I tend to stick with the much more compact and, on APS-C, more versatile, 50mm.
